vinylidene การใช้

• The cis-mono-bridged and vinylidene-like isomers are present.
• "Syntheses of neutral iron, ruthenium, and manganese half-sandwich vinylidene complexes.
• Saran wrap, formed from polymerization of vinyl chloride and vinylidene chloride, is an addition copolymer.
• Interest then moved to look at whether structures equivalent to vinylidene-Si = SiH 2-existed.
• VDF / HFP is a copolymer system of vinylidene fluoride and ( at least 20 % ) hexafluoropropylene.
• The comonomers vinyl chloride, vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties.
• It should not be confused with the vinylidene group = C = CH 2 or > C = CH 2.
• The original kind of cell named " lithium polymer " has technologically evolved from lithium-ion and poly ( vinylidene fluoride ) ( PVdF ).
• "' Polyvinylidene fluoride "', or polyvinylidene difluoride, ( "'PVDF "') is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride.
• Recent research with LB films and more conventional solvent formed films shows that the VDF copolymers ( consisting of 70 % vinylidene fluoride ( VDF ) and 30 % trifluoroethylene ( TrFE ) ) are promising materials for nonvolatile memory applications.
• The chemical properties of branched alpha-olefins with a branch at either the second ( vinylidene ) or the third carbon number are significantly different from the properties of linear alpha-olefins and those with branches on the fourth carbon number and further from the start of the chain.
• In addition to this, the positive electrode can be further decomposed in three parts : the lithium-transition-metal-oxide ( such as LiCoO 2 or LiMn 2 O 4 ), a conductive additive, and a polymer binder of poly ( vinylidene fluoride ) ( PVdF ).
• Other attempts to design a polymer electrolyte cell include the use of inorganic ionic liquids such as 1-butyl-3-methylimidazolium tetrafluoroborate ( [ BMIM ] BF 4 ) as a plasticizer in a microporous polymer matrix like poly ( vinylidene fluoride-co-hexafluoropropylene ) / poly ( methyl methacrylate ) ( PVDF-HFP / PMMA ).
• Viton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM . This class of elastomers is a family comprising copolymers of hexafluoropropylene ( HFP ) and vinylidene fluoride ( VDF or VF2 ), terpolymers of tetrafluoroethylene ( TFE ), vinylidene fluoride ( VDF ) and hexafluoropropylene ( HFP ) as well as perfluoromethylvinylether ( PMVE ) containing specialties.

• In appropriate contexts, methylidenecarbene can be viewed as ethene with two hydrogen atoms removed, or as ethane with four hydrogens removed; and as such, " ethen-1-ylidene " ( or " vinylidene " ) or " ethane-1-diylidene ", respectively, may be used as a context-specific systematic names, according to substitutive nomenclature.
